>You are so demanding when its bedtime !!!!<
I once had a Chinese girlfriend who used to say that to me :-)
And I've heard all the arguments about, "Avebury was also up and down and all around than in some tidy all up fashion that cuts right across and hides other histories and stories this landscape..." and it just doesn't cut the mustard any more.
You're right, of course, we'll probably never know what Avebury looked like at any specific place at any specific time but so what? You and I know there are stones down there under the turf so do you want to leave them there or do you want to put them up again? It's as simple as that. Forget about the chronology and all "that blackboard rubbish copied down." Do you want to see those stones standing again or not?
A yes or no will suffice.
